The Reed 4-in-1 Thru-Bolt ratchet wrench features four sockets on one wrench in a popular dog bone configuration. The sockets stay on the handle preventing loose sockets. The L4N1 offers rugged construction of its smooth grip handle with a forward/reverse pawl. One tool is all you need for mechanical joints and restraints, repair clamps, service saddles, gas/water couplings, flange bolts, friction clamps, hydrant break flanges and some bonnet bolts. Additionally, tightening nuts on long bolts or all-thread rod is never a problem with Reed’s Thru-Bolt socket which works by letting the bolt pass completely through the socket and arm head so nuts can be worked on any threaded length. Thru-bolt sockets replace the need for separate regular and deep sockets.
